摘要

在常见的Wi-Fi室内定位方法中，大部分研究聚焦于定位算法的精度，但是对于已有室内数据如何进行高效组织和处理，以实现室内位置服务的应用系统研究并不多。针对此类问题，将知识图谱与传统室内定位技术结合，并利用多种软件开发技术完整开发出实用的定位系统。融合了物理空间和信息空间，信息空间包含室内信息获取、云端服务、信息存储及计算部分，物理空间表达了室内空间结构及其数据关系。最后，通过WEBGL（web graphics library）技术进行直观的定位展示，以实现室内信号数据和定位结果的可视化。系统拥有完备的数据存储和使用机制，对室内物联网设备的已有数据信息整合后便可以为用户提供房间级位置服务，并且系统的分步定位功能有助于减少系统运算耗时。

Abstract

Among the common Wi-Fi indoor positioning methods

most of the research focuses on the positioning accuracy

a little is on the application system to organize and process the existing indoor data efficiently in order to realize the indoor location service.To deal with these issues

the knowledge graph with the traditional indoor positioning technology was combined

and a practical positioning system was built with a variety of software development technologies.The system integrates the physical space and the information space.The information space includes indoor information acquisition

cloud services

information storage and computing parts.The physical space expresses the structure of the indoor space and data relationships.Finally

the WEBGL technology was used to display intuitive positioning and realize the visualization of indoor signal data and positioning results.The system has a complete data storage and use mechanism.After integrating the existing data information of the indoor internet of things equipment

it can provide users with room-level location services.The step-by-step positioning function of the system helps to reduce the time consumption of the system.
